Hydro in closet(s)?!

Brand new grower here, thinking about doing hydro in a closet or two (maybe one veg one flower, or just one dual-purpose with a room for storage/curing/cloning?)

Anyways. . . I have been looking at making a system similar to the AA EconoJet 22" but with individual parts, and getting a short/fat res (more on that later). I would use Rockwool for starters, and clay pebbles for the other medium (identical to Mr. Green's Flower room on his video). Would that be advisable to use in a small closet space like that? I can easily control the temp/humidity.

Alright, now for the shitty part! I have two separate closets, each 31"W x 25"D x 61"H (hence why wanting as short a res as I can, and only using the 22" tray). Also, I have a 5 foot height between the floor and where the light will have to hang. I know I can probably only hold about 4 short plants in that space, but that isn't too bad.

I would really like to make one a veg room and one a flower room, but that would mean buying/making 2 hydro tables, and more lighting shit. I think I could rig one squirrel cage to exhaust both closets, but it would obviously be easier to exhaust one room. I am still weighing the pros/cons for each, but I hope to get a little experienced insight here.

Absolutely any criticisms and suggestions are welcome, I am still learning!

Thanks!

check out my journal..i just added a hydro set up to it..
Cali's Kush Journal..20 Clones/1000 Watts.

Alright, I have been looking around more and I think I am actually going to make two bubbler systems nearly identical to the Stealth Bubbleponics Kits. One for vegging and one for flowering, since I have the two identical closets, it's perfect for having a room dedicated for each, that way I can have a perpetual grow setup.

Going to get a 400W MH w/ Batwing reflector for the vegging and a 400W HPS w/ Batwing for flowering. I only have a crappy CFL right now for a small 3-plant soil grow I am finishing up (sorry, no pics of that one) and I want something beefier for my hydro adventures.

The only things I am really unsure of now are what nutes to use, but to be honest I haven't really looked into those too much at all. I just know I probably don't want organics for the hydro setup. What are some good nutes anybody can recommend? I know I could go digging around reading 50+ page journals, but. . .

Thanks all!

EDIT: LOL I forgot I had a couple crappy cellphone pics of the early stages of my soil grow. The pics I attached are from November 8th, but those plants are done and smoked already.
